Abstract

Introduction and Background. This work is part of the SILK project which aims at supporting semantic integration using logic programming [2]. The main idea of our approach is to collect and manage meta-information on the sources to be integrated. These pieces of information are stored in the model warehouse of the SILK system in the form of models, constraints and mappings. By using logic, all these are represented in a uniform way.
